摘要： A method is described for enhancing a digital image channel, particularly where the digital image channel is split into pedestal and texture signals that substantially comprise the digital image channel. The method utilizes a predetermined tone scale conversion to enhance the digital image channel. Initially, image values are provided from the pedestal signal corresponding to image pixels from a region of the image. Then, a statistical characteristic of the image pixels in the region is identified, and the predetermined tone scale conversion is normalized for the statistical characteristic in order to generate a normalized tone scale conversion. The normalized tone scale conversion is then performed on a central pixel of the region in order to generate a pedestal signal with enhanced image values; and the pedestal signal with enhanced image values is combined with the texture signal to generate an enhanced digital image channel.

摘要： A method for utilizing a predetermined tone scale conversion to enhance a digital image comprised of a plurality of image pixels, each image pixel characterized by an image value, includes the steps of providing image pixels corresponding to a region of the image; identifying a statistical characteristic of the image pixels in the region; normalizing the predetermined tone scale conversion for the statistical characteristic in order to generate a normalized tone scale conversion; and performing the normalized tone scale conversion on a central pixel of the region in order to generate an enhanced output pixel. In one embodiment, a scaling function is generated based upon the statistical parameter and a first intermediate value is generated from application of the scaling function to the input pixel value. Then a second intermediate value is generated from the application of the first intermediate value to the tone scale function, and an enhanced pixel value is then obtained from application of the inverse of the scaling function to the second intermediate value.

摘要： An electronic imaging system useful for compositing images includes an electronic camera for capturing multiple images, including a first image of a subject plus background and a second image of the background only. The first and second images are subtracted to generate a difference image, and the difference image is processed to generate a mask image. The mask image is then applied to the first image to select an area in which the subject is located, whereby the selected subject area is used in the compositing of a new image.
